Inspecting and characterizing surface quality of finished optical components e.g.: lenses, prisms, mirrors, reticles, windows and wedges in accordance with MIL-13830, MIL-C-48497 and the new ANSI/OEOSC OP1.002:2008 is easily accomplished using these Scratch/Dig Sample Sets. The samples serve as direct visual comparison standards.
Davidson Optronics Model D-727 Scratch Samples meet ASTM Scratch Test Standard (Glass) adjunct F-428. They are approved by the ASTM F07.08 committee for the surface finish characterization of aircraft windows.
